What does GFR MDRD mean?

What does GFR MDRD mean?

In adults, the most widely-used equations for estimating glomerular filtration rate (GFR) from serum creatinine are the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation1 and the isotope dilution mass spectrometry (IDMS) traceable Modification of Diet in Renal Disease (MDRD) Study equation2.

What is the MDRD formula?

Another formula was derived from data collected in the Modification of Diet in Renal Disease (MDRD) study. The MDRD formula, also called the Levey formula, is now widely accepted as more accurate than the Cockcroft and Gault formula and is considered an alternative to radioisotope clearance.

What is the normal range for eGFR?

A normal eGFR is 60 or more. If your eGFR is less than 60 for three months or more, your kidneys may not be working well.

What is the eGFR equation?

GFR = 141 × (Scr/0.9)-1.209 × (0.993)Age. CKD-EPI equation expressed as a single equation: GFR = 141 × min (Scr /κ, 1)α × max(Scr /κ, 1)-1.209 × 0.993Age × 1.018 [if female] × 1.159 [if black]

Should I worry if my GFR is 56?

A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure.

Why is my GFR low for my age?

GFR gets lower with age, even in people without kidney disease. The older you are, the lower your GFR. For this reason, the GFR calculation accounts for age. At any age, a GFR below 60 for three months or more indicates kidney disease.

Is there a calculator for MDRD?

MDRD Calculator. This MDRD calculator estimates rate of glomerular filtration (GFR) based on serum creatinine, patient data and the Modification of Diet in Renal Disease formula. Below the form there is more information on the MDRD equation and an interpretation of GFR values correlated with CKD. Ads.

When to use the IDMS-traceable MDRD Study Equation Calculator?

This IDMS-traceable MDRD study equation calculator is for use when S cr is reported in mg/dL. This equation should not be used when eGFR values above 60 mL/min/1.73 m² are desired. GFR (mL/min/1.73 m²) = 175 × (S cr) -1.154 × (Age) -0.203 × (0.742 if female) × (1.212 if African American) (conventional units)

What is the MDRD formula for GFR?

MDRD 4-variable GFR Equation GFR in mL/min per 1.73 m 2 = 175 x SerumCr -1.154 x age -0.203 x 1.212 (if patient is black) x 0.742 (if female) Notes: The original Modification of Diet in Renal Disease (MDRD) equation was based on 6 variables: age, sex, ethnicity, serum creatinine, urea, and albumin (often referred to as MDRD 6).

What is the MDRD equation for renal disease?
